The Chicago Bears and their new head coach Marc Trestman put a wrap on their 14-practice, training-camp stint in Bourbonnais with a light workout in shorts and helmets Tuesday.

Now it’s on to preseason Game No. 2 on Thursday night, and then the team moves into the newly renovated Halas Hall facilities at Lake Forest.

But did Trestman and his staff of young go-getter coaches see enough in Bourbonnais to get a good feel for what this team will bring to the table in 2013?

Here are some of the things we’ve picked up in Bourbonnais that may help us better answer that question, and more:

-- The offense as a whole is still very much a work in progress. While a couple of pieces have been added — most noticeably, tight end Martellus Bennett is going to upgrade that position dramatically — other problem areas have not, namely the offensive line.

“When you’re a new staff on a new team, it’s going to come slow,” offensive coordinator Aaron Kromer said. “We’re trying to get a feel for the players and what they do best, and we have to continue to do that.

— While Brandon Marshall is still going to catch a lot of Jay Cutler passes, the entire team — Marshall included — hopes more players get involved. Bennett will be big in this department, and second-year wideout Alshon Jeffery appears to be morphing into a weapon as well. But after that, it’s thin.

“We’re seeing what some of the other guys can do right now,” Cutler said. “We’re moving along. I don’t think I can pinpoint exactly where we’re at. There’s positives and negatives.”

Earl Bennett was concussed early in camp, and Devin Aromashodu, Eric Weems, Joe Anderson and rookie Marquess Wilson are in the mix. But no one has taken that huge leap that makes a coaches’ job easier. Pretty soon, a couple of those guys will be looking for jobs.

“I think there are a lot of guys at the wide receiver position that are showing spurts,” Kromer said, “but they all need to be more consistent.”

— Trestman has given the reins of this defense to coordinator Mel Tucker, and he’s made a nice transition. The defense, which lost Brian Urlacher, but little else, appears to be ready to go. The defense is almost always ahead of the offense in the preseason, especially when a new system is installed. But the Bears’ D has manhandled its teammates in at least 10 of the 14 practices, and the question of whether ”the defense is that good, or the offense is that bad” continues to linger.

— But despite all this, the thing we’ve learned most from Bourbonnais is that we really haven’t learned much at all.

The offensive line is still in shambles; the defense will be good-to-excellent again; and the pressure is on Cutler to produce, but he looks like the same Cutler we’ve seen the past three seasons.

“There’s ups and downs. Some of the plays look good, some of the plays not so good,” Cutler said after Tuesday’s practice. “It’s just dealing with those, and bouncing back for the next play.”

It’s time for some of that bouncing back to show. The Bears have three more preseason games, and more than three weeks of practice. There is still time, and there is still hope. But with every passing practice — and every pretend sack in team drills — the hope fades just a bit.

“It won’t be the same team as it was last year,” Trestman said, “but we think it can be better.”

We can only hope we learn more over the next three weeks than we did in the first three of the Trestman regime.
